供水水量产销差和漏损率分析与控制对策

该文介绍了产销差、漏损率和漏损指数等3项指标的原理与计算方法,以及国内外城市产销差和漏损率现状,重点分析了上水市南十一五期间的产销差和漏损率,得到年均值分别为18.08%和17.98%,根据相关标准提出漏损率控制目标为14%。参考国际水协的水量平衡表,提出了从免费用水量、表观漏损和真实漏损等三个方面控制的方法与措施。

Analysis and Control Countermeasures for Non-Revenue Water and Rate of Leakage & Loss of Water Quantity Supplied

The principle and calculation method such as non-revenue water,rate of leakage loss infrastructure leakage index as well as the present status at home and abroad were introduced.The annual average values of non-revenue water and rate of leakage and loss,which were 18.08 % and 17.98 % respectively,in the 11th five-year plan in Shanghai Municipal Water Works South Co.,Ltd.,were analyzed.Based on the correlation standards,the control objective was aimed at 14 %.According to the water balance sheet from the International Water Association,leakage control methods and measures such as authorized consumption,apparent losses and real losses,were proposed.
